Can't login after changing the base currency, i have registered a customer when base currency USD. And after i changer the base currency to EURO i cant login with that customer account, its keeps loading but nothing comes. After a while it throws an error on "memory exhausted". But the same user can login when the base currency is USD. I've looked into the exception and system log files as well. No clue as to what is causing this issue.
Basically we are trying to implement Currency switcher, it works well for guest users. But doesn't work when the user is trying to login and the current currency does not match to the currency at the time of user registration.
FYI : magento version is 1.9.2 CE
